URL for the starting image. Use high-quality images for better transitions.
URL for the ending image. High-quality images enhance visual transitions.
Video length in seconds. Choose 5 for quick previews, 8 for detailed animations.
Allowed values:
Animation theme description. Try thematic prompts for creative animations.
Video resolution. Use 1080p for high quality, 360p for fast previews.
Allowed values:
Seed for repeat results. Change for unique animations.
min : 1,
max : 999999
Animation motion style. 'Normal' is smooth, 'fast' is rapid.
Allowed values:
To keep track of your credit usage, you can inspect the response headers of each API call. The x-remaining-credits property will indicate the number of remaining credits in your account. Ensure you monitor this value to avoid any disruptions in your API usage.

PixVerse V4: Effective Usage Guide
PixVerse V4 empowers developers, creators, and executives at Segmind with cutting-edge AI video generation. This guide walks you through best practices, parameter selections, and workflows to maximize output quality and creative impact.
1. Core Parameter Overview
- •first_frame_url & last_frame_url: High-resolution images (≥1080px) yield smoother transitions.
- •prompt: Concise, descriptive text drives theme, style, and mood (“neon cityscape at dusk”).
- •duration: Dropdown [5, 8] seconds.
- •quality: Dropdown [360p, 540p, 720p, 1080p].
- •motion_mode: “normal” for fluid animations, “fast” for energetic motion.
- •seed: Integer [1–999999] for reproducibility or varied outputs.
2. Quick Previews vs. Final Renders
Use shorter, lower-res clips to iterate rapidly, then upscale for final delivery:
| Use Case | duration | quality | motion_mode | seed |
|---|---|---|---|---|
| Rapid Prototyping | 5 sec | 360p | fast | random |
| Detailed Preview | 8 sec | 540p | normal | fixed |
| Final Cinematic | 8 sec | 1080p | normal | fixed |
Example JSON for a detailed preview:
{
"first_frame_url": "https://…-first-frame.webp",
"last_frame_url": "https://…-last-frame.webp",
"prompt": "Futuristic robot assembling a spacecraft in low light",
"duration": 8,
"quality": "540p",
"motion_mode": "normal",
"seed": 424242
}
3. Advanced Prompt Engineering
- •Style Tags: Append “—anime”, “—cinematic lens”, or “—documentary” in the prompt.
- •Multi-Image References: Supply varied stills under
first_frame_url/last_frame_urlto anchor complex visuals. - •Iterative Refinement: Tweak adjectives (color temperature, pacing) and rerun for fine-tuned animations.
4. Use Case Tailoring
- •Social Media Shorts:
• duration=5, quality=360p, motion_mode=fast, seed=random
• Prompt with trending keywords: “dance montage in neon club” - •Product Demos:
• duration=8, quality=720p, motion_mode=normal, seed=123456
• Use high-res product images as frames and “—macro lens” styling - •Educational Explainers:
• duration=8, quality=1080p, motion_mode=normal
• Prompt: “diagram transitions illustrating photosynthesis steps”
5. Workflow Tips
- •Always start with a small batch: experiment on low-res previews.
- •Lock the seed for consistent A/B testing.
- •Leverage cinematic lens controls and motion_mode to match narrative pacing.
By aligning PixVerse V4’s parameters with your project goals, you’ll unlock high-quality, dynamic videos that elevate your brand storytelling and creative output.
